The study involved two main subject groups: (1) convicted juvenile burglars and (2) adult householders. Subjects were presented with photographs of houses and asked whether or not they would choose them as a burglary target on the basis of the information available. These photographs were identical for each subject apart from a controlled factor. Data also were gathered from participants via a checklist procedure, a short interview, and a surprise recognition test. The findings indicated that young burglars largely concurred as to the factors which influenced their decision when choosing a target. However, their choice of factors differed in several important respects from those which householders believed to be important to such offenders. The implications of this work for environmental crime prevention strategies are discussed. (Author abstract)
